Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1 and 4, a pipe socket structure includes a pipe socket 10 and a pipe insertion opening 20.

Referring to fig. 2 and 5, an inner annular groove 11 is formed on an inner wall of the pipe socket 10, and a first sealing groove 111 is formed on a bottom surface of the inner annular groove 11. An outer ring groove 21 is formed in the outer wall of the pipe body insertion opening 20, and a second sealing groove 211 is formed in the bottom surface of the outer ring groove 21.

The pipe socket structure further includes a first seal ring 30 disposed in the first seal groove 111, and a second seal ring 40 disposed in the second seal groove 211. The pipe body socket 20 is inserted into the pipe body socket 10, the side wall of the inner annular groove 11 is closely attached to the side wall of the outer annular groove 21, the end surface of the pipe body socket 20 abuts against the first seal ring 30, and the end surface of the pipe body socket 10 abuts against the second seal ring 40.

The utility model discloses a pipeline socket structure, body socket 20

insert body bellmouth
